Our current front-line Heavy Rescue Squad is a 1994 Simon-Duplex/Saulsbury. The rear axle housing (Rockwell RS30-185) developed a split on the driver's side toward the front of the vehicle along the factory weld. We believe that the cause was the torque created by body movement allowed by the Ridewell Air Suspension. Our solution was to weld 1/4" AR-400 Hi Tensile strength plates to the top side of the axle housing on both sides. These plates help to distribute the imposed loads along the housing as opposed to the point loading before the plates were installed.
We are in the process of purchasing a new Heavy Rescue Squad, and neither the Chassis Manufacturer (Spartan) or Saulsbury feel there is a need to install these plates on the new rig. We'd like to know if anyone else out there has experienced a similar problem with cracking of the axle housing.
